"The Big Bang theory is simply preposterous.This is not chochmah, but rather, it is shtus"! (Rav Shimon Schwab, "Rav Schwab on Prayer", Artscroll 2001, page 444).
The Big Bang theory cannot be squared with the Breishis account. According to the Torah, all the elements were made together, the Earth was formed before the stars, plants were formed before the sun, birds were created before reptiles, and the Sun, Moon and stars were formed on the Fourth Day, after the Earth.
But according to the Big Bang theory, the elements beyond hydrogen and helium were formed after millions of years, the Earth was formed long after the stars, plants evolved after the Sun, birds evolved from reptiles, and the Sun was formed before the Earth!
The Big Bang theory was originally conceived out of a desire to have a godless naturalistic explanation for the origin of the universe. A modified view has it that when the explosive event happened, it was directed by G-d. This is called theistic evolution and is an attempt to compromise the Torah with vast-age evolutionary theories, and is currently in vogue in some Orthodox circles.
All the many stars appeared suddenly and supernaturally in space. Scripture does not imply an explosion, which would have propelled all matter radially from its center, and by the Law of Conservation of Angular Momentum, could not have acquired the curving rotations and orbits we see everywhere in the cosmos. Worse, the Big Bang theory blatantly contradicts Newton's Law's of Motion and the Laws of Thermodynamics that state that with the passing of time there is an increase in entropy (disorder): there is a deterioration as systems go from order to disorder.
The Big Bang model requires belief in such arcane notions as "dark matter", "dark energy", "curved space", "neutron stars", "black holes", "superluminal jets", and "variously flavoured neutrinos", all theoretical entities that were invented in order to save the model from contradicting observations, and that have never been observed or photographed.
It is intellectually dishonest to conjure up the existence of unobservable entities in order to save a theory that observation would otherwise disprove.
At the time of Creation "He spoke and it was; He commanded and it stood firm" (Tehillim 33)! The astronomical data once claimed to be evidence for the Big Bang theory, such as the Redshift and the Comic Background Radiation, instead support a rapid fully formed Geocentric creation that took place only thousands of years ago!
